Abstract :
Composting is a way of treating organic waste biologically, using microbial
activity to convert organic waste into material with soil characteristic. Filter cake
from sugar factory has carbon, nitrogen, phosphate, calium and the other minerals
that can be use for soil recovery for example high water holding capacity. The goal of
research is to use organic waste for green manure. The waste from sugar factory is
filtercake that mix with rubbish.
This research use aerobic system, with variant of filter cake add are 1 kg, 2 kg,
3 kg and 4 kg. Use aeration method without aerator and with aerator use variant of
dosis are 1,8; 2,7 and 3,6 l/min/kgVs. Rubbish with 3 kg weight without filter cake
add as control.
The result of the research is 4 kg filter cake add each 3 kg rubbish stimulation
decrease of C/N ratio 19,2. Aeration method that effective for composting is use
aerator. The microbial growth influence decrease of C/N ratio during composting
with 84 % decrease.
